Renthal Ultralight Rear Sprockets start their lives off by getting CNC machined from 7075 T-6 aluminum, an alloy that is prized for its strength and wear resistance. A near perfect material for sprockets. The alloy is light weight, and with Renthal’s drilled patterns, the Ultralight weighs up to 66 percent less than comparable steel sprockets while retaining a comparable lifespan. The material isn’t the only thing that promotes longevity. Self-cleaning cuts are machined into each chain groove to clear away mud and debris from sensitive wearing surfaces, so both the sprocket and chain are kept clean of abrasive particles. There’s almost no downside to putting a Renthal Rear Sprocket on your motorcycle or ATV.

With 7 world titles and the 2007 Dakar Rally under its belt, why would you choose anything besides the Stealth Rear Sprocket from Supersprox?
The Stealth will outlast your all aluminum sprocket by 300% and undercut the weight of your steel sprocket by 50%. How? Supersprox makes the Stealth using a unique, two piece design that combines a 7075 T6 aluminum alloy inner hub and an electro-less nickel coated, carbon steel outer ring to bring out the best of both materials. That means you get more strength and less weight. You’re getting your cake and you’re going to eat it too. The cherry Supersprox puts on top is that the Stealth bolts to your stock hub, looks great, and comes designed to work perfectly with your motorcycle or ATV.
Specs: *Unique 2-piece design *Has benefits of both steel and aluminum sprockets *Outlasts aluminum sprocket by 300% *Fits just like a stock sprocket *Weighs 50% less than all steel sprockets *7075 T6 aluminum inner hub *Electro-less nickel coated carbon steel outer ring
Supersprox goes all out with their Rear Steel Sprockets, from first stage to last. Let’s start with the first. Supersprox begins by using a highly specialized SCM435 Ni-Chrome-Molybdenum low-corrosion type steel as the base material for the sprocket. Once the shape has been CNC machined, the sprocket is case hardened to give it a low carbon core and an incredibly tough surface hardness. To finish it off Supersprox uses hot-dip galvanizing to protect the surface of the sprocket by chemically creating a shielding layer of zinc carbonate. So what does all that mean? What it means is that you’re getting a sprocket with outstanding durability made from some of the best materials available.

Renthal’s Twinring Rear Sprocket puts new innovation and engineering into your drivetrain for outstanding durability. What sets Renthal’s Twinring sprocket apart is its unique construction combining a 7075 T651 aluminum inner ring, with an electroless nickel coated steel outer sprocket using a wave-patterned interference fit. This design combines the high wear-resistance of steel and the light weight of aluminum to create a sprocket that handles huge amounts of power while weighing half of conventional, all-steel sprockets. The flat-faced design also helps keep weight down while working with the self-cleaning chain grooves to keep the chain free of any abrasive buildup.
With 5 years of development and testing by Team Honda Off-road, Renthal’s Twinring gives you extreme durability and feather-light weight. You get the best of both worlds in one sprocket.
